Multi-factor biometric authentication

Abstract

Technology for an electronic device is described. The electronic device can include a fingerprint sensor, a heart rate sensor, and a controller. The controller can receive a fingerprint of a user captured using the fingerprint sensor. The controller can determine whether the fingerprint of the user matches a predefined fingerprint stored in a data store of the electronic device. The controller can receive heart rate information of the user captured using the heart rate sensor. The controller can determine whether the heart rate information is within a defined range. The controller can unlock the electronic device to allow the user to access the electronic device when the fingerprint of the user matches the predefined fingerprint stored in the data store and the heart rate information is within the defined range.
